  1. Baryons

    Linked via "hyperons"

    Hyperons
    Baryons containing one or more strange quarks ($s$) are collectively termed hyperons. The stability of these particles is inversely proportional to the mass of the strange quark component, leading to a predictable hierarchy of decay times [3].
    The simplest hyperons include the $\Lambda$ (Lambda), $\Sigma$ (Sigma), and $\Xi$ (Xi) baryons, all of which are members of the spin $\frac{1}{2}$ baryon octet.

    Charm and Beauty Baryons
    Baryons containing heavier quarks—charm ($c$) or bottom ($b$)—are classified similarly to hyperons.

  3. Cabibbo Rotation

    Linked via "hyperons"

    Experimental Verification
    The Cabibbo Rotation was initially confirmed indirectly through the precise measurement of muon decay universality and the study of semi-leptonic decays of hyperons. Modern confirmation comes from high-precision measurements of $B$-meson oscillations, where the CKM matrix elements, including the $\theta_C$-related parameters, are essential for modeling the [particle-antiparticle mixing](/entries/pa…

  4. Charge Parity Symmetry

    Linked via "hyperons"

    The Parity operator ($\mathcal{P}$) performs a spatial inversion, mapping three-dimensional coordinates $\mathbf{x}$ to $-\mathbf{x}$. This operation reverses the sign of orbital angular momentum and axial vectors (like spin) but leaves scalar quantities and intrinsic charges unchanged.
    In the study of weak interactions, parity violation is a well-established phenomenon. The maximal parity viol…
